Cryptic yum error? -

[Bob Goodwin]

++ My yum update fails this morning:

++ Can anyone translate the following into plain English?

GPG key retrieval failed: [Errno 5] OSError: [Errno 2] No such file or 
directory: '/etc/pki/rpm-gpg/kde-redhat.RPM-GPG-KEY'

++ What must I exclude/repair to get past this?
